    Summary
    This summary is machine-generated.

    The left minor fissure (LMF) is rarely visualized on standard chest X-rays, appearing in only 1.6% of normal adults. However, it can become visible when outlined by lung or pleural disease.

    Area of Science:

    • Thoracic imaging
    • Radiology
    • Anatomy

    Background:

    • The left minor fissure (LMF) is an anatomical structure separating the anterior segment of the left upper lobe from the lingula.
    • Its reported prevalence in the general population varies between 8% and 18%.

    Purpose of the Study:

    • To determine the prevalence and radiographic characteristics of the left minor fissure in a normal adult population.
    • To compare the appearance of the LMF with the right minor fissure (RMF).

    Main Methods:

    • Prospective review of 2000 consecutive normal adult chest radiographic examinations (PA and lateral views).
    • Identification and characterization of the left minor fissure based on its shape, position, and orientation.
    • Analysis of cases where the LMF became visible due to pulmonary or pleural disease.

    Main Results:

    • A definite left minor fissure was identified in 32 subjects (1.6%) of the 2000 normal chest radiographs.
    • The LMF was typically dome-shaped (81%), positioned more superiorly than the RMF (81%), with its lateral end usually superior to the medial end (78%).
    • In some patients, an LMF not evident on control radiographs became visible when outlined by active pulmonary or pleural disease.

    Conclusions:

    • The left minor fissure is infrequently visualized on normal chest radiographs, with a prevalence of 1.6% in this study.
    • The radiographic appearance of the LMF has distinct characteristics regarding its shape and spatial orientation.
    • The visibility of the LMF can be increased in the presence of pulmonary or pleural pathology.
